Affraid to Upgrade from FC9 to FC12

[Kevin O'Neil]

Greetings everyone,
I am hoping that someone can help me decide if I should upgrade or not. I am 
very afraid to upgrade when FC12 comes out because I have tweaked almost 
every part of FC9 to get it to work the way I want. It works 110% right now. 
Is there a security issue that I should be aware of?

I really am looking forward to some of the new features, but like the old 
saying goes "If it aint broke, don't fix it".

Thanks,
Kevin
